Description

Technical Field

[0001] The present invention relates to the field of adding to and removing from a heating furnace in the heating and forming section of glass products, and provides a handling device for the handling section of glass blanks. Background Art

[0002] Currently, in the spherical glass production process of most domestic factories, in the heating and forming section of glass products, after the glass products are cleaned, they need to enter the heating furnace forming equipment to be heated to 700 degrees Celsius and then taken out. Currently, these processes are all carried out by manually controlling the suction cup to pick up and place the glass, and the working environment is relatively harsh, and personal accidents are likely to occur. Summary of the Invention

[0003] The purpose of the present invention is to overcome the above deficiencies in the background art, and provide a handling device for the heating and forming section of glass products with a simple structure, high efficiency in adding and removing glass blanks from the heating furnace, automation, safety, reduction of manual operations, and improvement of product quality and productivity.

[0004] To achieve the above purposes, a handling device for the heating and forming section of glass products provided by the present invention mainly includes a glass feeding-into-heating-furnace device, a glass removing-from-heating-furnace device, and a control device.

[0005] The glass feeding-into-heating-furnace device is mainly completed by a flange-type acting cylinder installed on a fixed support plate of the guide rail of a high-speed synchronous belt slide with a guide rail. Through the movement of the cylinder, the suction cup can place the glass sucked from the conveyor belt into the heating furnace. And during continuous operation, its position and attitude need to change on the guide rail, and the limit on the slide is carried out through a limit switch.

[0006] The glass removing-from-heating-furnace device is also mainly completed by two acting cylinders installed on a fixed support plate of the guide rail of a high-speed synchronous belt slide with a guide rail. Through the movement of the two acting cylinders, the suction cup sucks the glass that has completed the heating process in the heating furnace, and then places it at the fixed placement position in the mold in the glass blank heating section, which is completed by the conveyor belt.

[0007] The control device mainly controls the glass feeding into and removing from the heating furnace differently. When the color sensor collects the signal of the glass feeding into the heating furnace (red signal), the pneumatic servo control system is used to control the commutation of the proportional flow valve, so as to realize the corresponding cylinder movement and achieve the work of feeding the glass into the heating furnace; when the color sensor collects the signal of the glass removing from the heating furnace (blue signal), the pneumatic servo control system is used to control the commutation of the proportional flow valve, so as to realize the corresponding cylinder movement and achieve the work of removing the glass from the heating furnace.

[0008] In the above solution, the flange-type cylinder in the glass loading heating furnace device is vertically installed on the fixed support plate of the guide rail of the high-speed synchronous belt slide with a guide rail, and a suction cup with a limit switch is connected to one side of its piston rod. When the glass in-place sensor detects that the glass on the conveyor belt is in place, the cylinder descends, and the suction cup approaches the glass blank input from the conveyor belt for the heating process. The contact of the limit switch senses the distance of the glass, so that the vacuum suction cup can grasp the glass ingredient on the conveyor belt. Then the synchronous belt slide drives the cylinder to move to the left in place of the heating furnace. The color sensor placed on the side surface of the heating furnace detects that the heating furnace rotates in place, the cylinder descends to release the vacuum suction cup, and the glass is placed on the heating furnace mold. The cylinder ascends to the in-place position, the synchronous belt slide drives the cylinder to move to the right in place, and the next repetitive action is continued.

[0009] In the above solution, the flange-type cylinder in the glass unloading heating furnace device is vertically installed on the fixed support plate of the guide rail of the high-speed synchronous belt slide with a guide rail, and a suction cup with a limit switch is connected to one side of its piston rod. When the color sensor placed on the side surface of the heating furnace detects that the heating furnace rotates in place, the cylinder descends to the in-place position. When the suction cup continuously approaches the glass on the heating furnace, the contact of the limit switch senses the distance of the glass, so that the vacuum suction cup sucks the glass. Then the cylinder ascends to the in-place position, the synchronous belt slide drives the cylinder to move to the right to a certain position, and the glass is placed on the conveyor belt. Under the rotation of the conveyor belt, the glass is flipped onto the conveyor belt to achieve the flipping and transporting action. The next repetitive action is also executed.

[0010] In the above solution, the control device is mainly used to control the movement of the cylinder for loading the glass into the heating furnace device and the cylinder for unloading the glass from the heating furnace device. When loading the glass into the heating furnace device, when the glass in-place sensor detects that the glass on the conveyor belt is in place, the air compressor generates compressed air, and after being processed by the pneumatic triple unit, the ideal compressed air is obtained. The pneumatic servo control system controls the left-position commutation of the proportional flow valve, then the compressed air enters the flange-type cylinder, thereby pushing the piston rod to move downward. The suction cup approaches the glass blank input from the conveyor belt for the heating process. The contact of the limit switch senses the distance of the glass, so that the vacuum suction cup can grasp the glass ingredient on the conveyor belt. Then the synchronous belt slide drives the cylinder to move to the left in place of the heating furnace. The color sensor placed on the side surface of the heating furnace detects that the heating furnace rotates in place, the pneumatic servo control system controls the right-position commutation of the proportional flow valve, the cylinder descends to release the vacuum suction cup, and the glass is placed on the heating furnace mold. Then the pneumatic servo control system controls the right-position commutation of the proportional flow valve, then the cylinder ascends to the in-place position, the synchronous belt slide drives the cylinder to move to the right in place, and the next repetitive action is continued.

[0011] In the above solution, in the glass discharging heating furnace device, when the color sensor detects that the heating furnace rotates into place, the proportional flow valve is controlled by the pneumatic servo control system to commutate to the left position, the cylinder descends into place, and the vacuum suction cup sucks the glass. At this time, the pneumatic servo control system controls the proportional flow valve to commutate to the right position, then the flanged cylinder ascends into place, and the synchronous slide table drives the cylinder to move right to a certain position, places the glass on the conveyor belt, and under the rotation of the conveyor belt, flips the glass onto the conveyor belt to achieve the flipping and transporting action. The next step also performs the repetitive action.

[0012] The comparison between the present invention and the current technology fully shows its superiority in that:

[0013] 1. In the glass feeding heating furnace device, a limit switch is adopted at the suction cup position on the piston rod side of the flanged cylinder. The contact of this device can sense the distance of the glass. When approaching the glass, the vacuum suction cup will open to suck up the glass, so that the suction can be carried out more automatically, avoiding accidents such as collisions with the glass.

[0014] 2. In the glass feeding heating furnace device, a color sensor is used to detect whether the heating furnace rotates into place, which can ensure the stability and accuracy of each glass feeding process into the heating furnace.

[0015] 3. In the glass feeding heating furnace device, a glass in-place sensor is adopted to accurately detect whether the glass blank conveyed from the conveyor belt is in place, improving the precision and accuracy of glass extraction.

[0016] 4. In the glass discharging heating furnace device, a limit switch is adopted at the suction cup position on the piston rod side of the flanged cylinder. The contact of this device can sense the distance of the glass. When approaching the glass, the vacuum suction cup will open to suck up the glass, so that the suction can be carried out more automatically, avoiding accidents such as collisions with the glass.

[0017] 5. In the glass discharging heating furnace device, a color sensor is used to detect whether the heating furnace rotates into place, which can ensure the stability and accuracy of each glass discharging process from the heating furnace.

[0018] 6. In the glass discharging heating furnace device, a glass transportation and flipping mechanism is adopted. Under the rotation of the conveyor belt, the glass can be flipped onto the conveyor belt to achieve the flipping and transporting action. The process of discharging the glass from the heating furnace can be continuously realized fully automatically.

Detailed implementation mode

[0031] The present invention will be further described in detail below with reference to the drawings and embodiments, but the embodiments should not be construed as limiting the present invention.

[0032] A glass product heating and forming section handling device provided by the present invention mainly includes a glass feeding into heating furnace device, a glass discharging from heating furnace device, and a control device.

[0033] The glass feeding into heating furnace device is mainly completed by a flange-type acting cylinder 4 installed on a fixed support plate 2 of a guide rail 1 of a high-speed synchronous belt slide with a guide rail. Through the movement of the cylinder, the suction cup can place the glass sucked from the conveyor belt into the heating furnace. And during continuous operation, its position and attitude need to change on the guide rail, and the limit on the slide is carried out through a limit switch 3.

[0034] The described glass unloading heating furnace device is also mainly completed by a flange-acting cylinder 13 installed on the fixed support plate 2 of the guide rail 1 of the high-speed synchronous belt slide with a guide rail. Through the movement of the cylinder, the suction cup sucks the glass that has completed the heating process in the heating furnace, and then places it at the fixed placement position in the mold in the glass blank heating section, which is completed by the conveyor belt.

[0035] The described control device mainly controls the glass loading and unloading of the heating furnace differently. When the color sensor 10 collects the signal of the glass being loaded into the heating furnace (red signal), the pneumatic servo control system is used to control the commutation of the proportional flow valve 7, thereby realizing the corresponding cylinder movement and realizing the work of loading the glass into the heating furnace; when the color sensor 10 collects the signal of the glass being unloaded from the heating furnace (blue signal), the pneumatic servo control system is used to control the commutation of the proportional flow valve 7, thereby realizing the corresponding cylinder movement and realizing the work of unloading the glass from the heating furnace.

[0036] In the above solution, the flange-type cylinder 4 in the glass loading heating furnace device is vertically installed on the fixed support plate 2 of the guide rail 1 of the high-speed synchronous belt slide with a guide rail, and one side of its piston rod is connected to a suction cup with a limit switch. When the glass in-place sensor detects that the glass on the conveyor belt is in place, the cylinder descends, and the suction cup approaches the glass blank that is input by the conveyor belt for the heating process. The contact of the limit switch senses the distance of the glass, so that the vacuum suction cup realizes the grasping of the glass batch on the conveyor belt.

[0037] Then the synchronous belt slide drives the cylinder to move left to the in-place position of the heating furnace. The color sensor 10 placed on the side surface of the heating furnace detects that the heating furnace has rotated in place. The cylinder descends to release the vacuum suction cup and places the glass on the heating furnace mold. The cylinder rises to the in-place position, and the synchronous belt slide drives the cylinder to move right to the in-place position, and continues to execute the next repeated action.

[0038] In the above solution, the flange-type cylinder 13 in the glass unloading heating furnace device is vertically installed on the fixed support plate of the guide rail of the high-speed synchronous belt slide with a guide rail, and one side of its piston rod is connected to a suction cup with a limit switch. When the color sensor placed on the side surface of the heating furnace detects that the heating furnace has rotated in place, the cylinder descends to the in-place position. When the suction cup continuously approaches the glass on the heating furnace, the contact of the limit switch senses the distance of the glass, so that the vacuum suction cup sucks the glass. Then the cylinder rises to the in-place position, and the synchronous belt slide drives the cylinder to move right to a certain position, places the glass on the conveyor belt, and under the rotation of the conveyor belt, flips the glass onto the conveyor belt to realize the flipping and transportation action. The next step also executes the repeated action.

[0039] In the above solution, the control device is mainly used to control the movement of the cylinder 4 for putting the glass into the heating furnace device and the cylinder 13 for taking the glass out of the heating furnace device. When the glass infeed sensor 12 detects that the conveyor belt glass 11 is in place during the process of putting the glass into the heating furnace device, the air compressor 5 generates compressed air, which is processed by the pneumatic triple unit 6 to obtain ideal compressed air. The pneumatic servo control system controls the left-position commutation operation of the proportional flow valve 7, then the compressed air enters the flange-type cylinder, thereby pushing the piston rod downward. The suction cup approaches the glass blank input from the conveyor belt for the heating process. The contact of the limit switch senses the distance of the glass, so that the vacuum suction cup can grasp the glass ingredient on the conveyor belt.

[0040] Then the synchronous belt slide drives the cylinder to move left to the heating furnace and be in place. The color sensor 10 placed on the side surface of the heating furnace detects that the heating furnace rotates to the in-place position. The pneumatic servo control system controls the right-position commutation operation of the proportional flow valve 7, and the cylinder lowers to release the vacuum suction cup, putting the glass on the heating furnace mold. Then the pneumatic servo control system controls the right-position commutation operation of the proportional flow valve 7, then the cylinder rises to the in-place position, the synchronous belt slide drives the cylinder to move right to the in-place position, and continues to execute the next repeated action.

[0041] In the above solution, in the process of taking the glass out of the heating furnace device by the control device, when the color sensor detects that the heating furnace rotates to the in-place position, the pneumatic servo control system controls the left-position commutation operation of the proportional flow valve, the cylinder lowers to the in-place position, and the vacuum suction cup sucks the glass. At this time, the pneumatic servo control system controls the right-position commutation operation of the proportional flow valve, then the flange-type cylinder rises to the in-place position, the synchronous slide drives the cylinder to move right to a certain position, puts the glass on the conveyor belt 15, and under the rotation of the conveyor belt 15, flips the glass to the conveyor belt 16 to realize the flipping and transporting action, and the next step also executes the repeated action.

[0042] The above device for the heating and forming section of glass products is not only applicable to the industries of adding glass to and taking glass out of the heating furnace, but also applicable to the situations of handling and transporting in other industries such as small materials and chemical materials.

[0043] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
